Firs (Abies) square measure a genus of 48–56 species of evergreen cone-bearing trees within the pine family. They're found through a lot of North and Central America, Europe, Asia, and geographic area, occurring in mountains over most of them vary. Fir square measure most closely associated with the gymnosperm genus (cedar). Douglas firs don't seem to be true firs, being of the Pseudotsuga.
They are massive trees, reaching heights of 10–80 m (33–262 ft.) tall with trunk diameters of 0.5–4 m (1 foot eight in–13 foot one in) once mature. Fir is distinguished from different members of the gymnosperm family by the approach within which their needle-like leaves square measure hooked up individually to the branches with a base resembling a suction cup, and by their cones, which, like those of true cedars (Cedrus), stand upright on the branches like candles and disintegrate at maturity.
The leaves have 2 whitish lines on the lowest, every of that is created by wax-covered stomatal bands. In most species, the side of the leaves is uniformly inexperienced and glossy, while not stomata or with a number of on the tip, visible as whitish spots. Different species have the side of leaves uninteresting, grey-green or bluish-grey to silvery (glaucous), coated with wax with a variable variety of stomatal bands, and not invariably continuous. AN example species with shiny inexperienced leaves could be a. Alba and an example species with uninteresting waxy leaves could be a. concolor.
The tips of leaves square measure are sometimes additional or less notched (as in an exceedingly. firm), however typically rounded or uninteresting (as in an exceedingly. concolor, A. magnifica) or sharp and prickly (as in an exceedingly. bracteata, A. cephalonica, A. holophylla). The leaves of young plants square measure sometimes sharpie. The wood of most firs is taken into account unsuitable for general timber use and is usually used as pulp or for the manufacture of plyboard and rough timber. As a result of this genus has no insect or decay resistance qualities when work, it's typically suggested in construction functions for indoor use solely (e.g. indoor drywall on framing). Firwood left outside cannot be expected to last quite twelve to eighteen months, looking on the sort of climate it's exposed to.
